The Most Overlooked Tax Strategy for Self-Employed Professionals

If you’re self-employed and focused only on deductions and 401(k) contributions, you may be leaving tens of thousands of dollars on the table every year. After more than 30 years advising business owners — and being self-employed myself — I’ve seen one strategy consistently outperform all others for high-earning solo professionals: the Defined Benefit Plan.

It’s not new. It’s not complicated. But it is profoundly underused.

What Most Self-Employed Professionals Focus On (And Why It’s Not Enough)

When tax season rolls around, the typical self-employed professional reaches for the familiar playbook: maximize business deductions, track every expense, and contribute to a SEP-IRA or Solo 401(k). These are all smart moves, and they absolutely belong in your financial strategy.

But here’s the honest truth — they’re incremental. They shave dollars off your tax bill rather than fundamentally reshaping your financial future.

The most impactful strategies are often the least understood. And in my experience, Defined Benefit plans sit at the very top of that list.

What Is a Defined Benefit Plan?

A Defined Benefit (DB) plan is a type of qualified retirement plan that allows self-employed individuals and small business owners to contribute — and deduct — significantly larger amounts than traditional retirement accounts.

Unlike a 401(k) or SEP-IRA, where contribution limits are fixed by the IRS each year, a Defined Benefit plan determines contributions based on a formula tied to your income, your age, and your desired retirement benefit. The goal of the plan is to fund a specific monthly income at retirement, and the contribution needed to reach that goal is what you get to deduct.

The result? Depending on your situation, you may be able to contribute and deduct $100,000, $200,000, or even more per year — far exceeding what any other retirement vehicle allows.

How Much Can You Actually Contribute?

Under current IRS rules, a Defined Benefit plan can be structured to fund a retirement benefit of up to $275,000 per year (indexed for inflation). The annual contribution required — and thus the tax deduction available — depends heavily on how old you are and how many years remain until retirement.

Here’s what that means in practical terms:

• A 45-year-old earning $400,000 might be able to contribute and deduct $130,000–$160,000 annually.
• A 55-year-old in the same situation might be able to contribute even more — because there are fewer years left to accumulate the target benefit.
• By contrast, the 2024 Solo 401(k) contribution limit is $69,000 (including catch-up contributions for those over 50).

Who Benefits Most From a Defined Benefit Plan?

Defined Benefit plans work especially well for a specific type of professional. You’re likely an ideal candidate if you are:

• A consultant, attorney, physician, or other solo professional with a well-established practice and consistent income stream.
• In your peak earning years — typically your mid-40s through early 60s. The older you are when you establish the plan, the higher your required annual contribution and the larger your deduction.
• Carrying a significant tax burden — in the 32%, 35%, or 37% federal bracket, especially in a high-tax state.
• Looking to retire within the next 10–20 years, with a clear time horizon.
• Self-employed with no or few employees. Employee coverage requirements can change the economics for larger teams.

The Three Core Benefits of a Defined Benefit Plan

1. Greater Tax Reduction — Now

Every dollar you contribute to a Defined Benefit plan is a dollar that doesn’t get taxed at your marginal rate today. For someone in the top federal bracket at 37% — plus state income taxes — a $150,000 deduction could mean more than $60,000 in immediate tax savings in a single year. That’s not a rounding error. That’s capital that compounds in your favor instead of being handed over to the IRS.

2. Accelerated, Tax-Deferred Wealth Accumulation

The money inside a Defined Benefit plan grows completely tax-deferred. You pay no taxes on investment gains, dividends, or interest until you begin taking distributions in retirement — ideally at a lower tax rate than during your earning years. For high earners who are already maximizing other accounts, a DB plan opens an entirely new and much larger tax-deferred bucket to invest in.

3. Better Use of Your Peak Earning Years

Peak earning years are a finite window. Many self-employed professionals reach their highest income levels between the ages of 45 and 65 — and then wonder, in hindsight, why they didn’t shelter more of it. A Defined Benefit plan is specifically designed to help you make the most of those years.

Defined Benefit Plans vs. Other Retirement Accounts

Many high-income professionals combine a Defined Benefit plan with a Solo 401(k) for maximum contribution potential. Used together, these vehicles can shelter an extraordinary amount of income from current taxation.

The Cumulative Effect: Reduced Lifetime Taxes and Accelerated Wealth

Consider a professional who establishes a Defined Benefit plan at age 50 and contributes $150,000 per year for 15 years, at a 35% effective tax rate:

• Total tax savings: Approximately $787,500 in deferred taxes
• Total contributions: $2,250,000 growing tax-deferred
• Compounded growth: Potentially $3.5 million or more at retirement, depending on investment returns

This is what strategic planning looks like, as opposed to simple tax reduction.

Common Questions About Defined Benefit Plans

Is a Defined Benefit plan complicated to set up?

The plan requires an actuarial calculation each year to determine the required contribution amount, and it must be established with the help of a qualified financial professional or TPA (Third Party Administrator). However, the administrative burden is modest relative to the tax savings involved.

Can I change my contribution each year?

To a limited extent, yes. The actuarial calculation allows for some flexibility, but Defined Benefit plans do require a consistent level of annual funding. They work best for professionals with stable, predictable income.

What happens when I retire?

At retirement, you can take distributions as regular income (taxed at your then-current rate), roll the plan balance into an IRA, or in some cases purchase an annuity. The flexibility at distribution is meaningful.

Is this only for the very wealthy?

Not at all. Defined Benefit plans are most beneficial for self-employed professionals earning $200,000 or more annually. If you’re in a high tax bracket and looking for a meaningful way to reduce your tax liability and accelerate retirement savings, this conversation is worth having.

A Shift in Thinking: From Tax Reduction to Strategic Planning

Most tax strategies ask: How do I reduce what I owe this year?

A Defined Benefit plan asks a better question: How do I build the most wealth over my lifetime while minimizing the total taxes I pay?

That shift in perspective is what separates tactical thinking from strategic planning. After three decades of working with business owners and high-income professionals, I’ve seen this strategy change lives — not in a dramatic, overnight way, but in the quiet, compounding way that genuine financial security is built.

Is a Defined Benefit Plan Right for You?

If you’re a self-employed professional with stable income, a significant tax burden, and a desire to make the most of your peak earning years, a Defined Benefit plan deserves a serious look.

The best next step is a conversation with a financial advisor who specializes in tax-advantaged retirement strategies for self-employed professionals. Bring your most recent tax return, your current retirement account balances, and a sense of when you’d like to retire. From there, the numbers will tell a compelling story.

You’ve worked hard to build a successful practice or business. A Defined Benefit plan is one of the most powerful tools available to make sure that success is protected — and multiplied.
